Previously, MB IEs were parsed only from association event. Try to get
MB IEs from other management frames like Probe Response frames. The MB
IEs from the association event may not be up-to-date and in some cases
may actually be missing and updating the information based on other

This allows offloaded roaming to inform user space of the change in IP
subnet post roaming. The device may have roamed to a network which is in
a different subnet which will result in IP connectivity loss. Indicating
the change in subnet enables the user space to refresh the IP address or
to perform IP subnet validation if unknown status is indicated.
The driver indication is reported with a new event from wpa_supplicant
in the following format:
CTRL-EVENT-SUBNET-STATUS-UPDATE status=<0/1/2>
where
0 = unknown
1 = IP subnet unchanged (can continue to use the old IP address)
2 = IP subnet changed (need to get a new IP address)

If "STA_AUTOCONNECT 0" has been used to disable automatic connection on
disconnection event and the driver indicates a failure for the data
connection after successful WPS handshake, it is possible to hit a case
where wpa_s->disconnected is set to 1 and further attempts to connect
shall stop.
While "STA_AUTOCONNECT 0" is used to disable automatic reconnection
attempts in general, this specific WPS case can benefit from trying
again even with that configuration for a short period of time. Extend

It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.
Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same
BSS.

The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.
Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message

Previously, within-ESS roaming was skipped if the selected BSS did not
have a higher signal strength than the current BSS regardless of AP
capabilities. This could result in not moving to a BSS that would
provide higher throughput, e.g., due to larger channel bandwidth or
higher rates (HT/VHT MCS).

allow within-ESS roaming if the selected BSS is likely to provide better
throughput even if the current BSS has larger RSSI.

When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when
roaming candidates are evaluated, the RSSI value of the current BSS used
to compare is an old one obtained during the last scan rather than the
new one given by the signal change event. This leads sometimes to bad
decision when selecting a new BSS for roaming.
This patch solves the issue by updating the current BSS level when
receiving a signal change event in order to have a very up-to-date
current signal value when choosing an new BSS.

If a separate P2P group interface was used, P2P_CONNECT-auto fallback to

need to reply to PD Request to allow this code path to be triggered.
When five scans for the GO were completed in this sequence, the P2P
group interface was removed as part of falling back to GO Negotiation.

While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.
Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.
To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.
If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.
In addition to this change, RSSI threshold limit is passed as part of
start sched_scan request. This was previously set only in pno_start(),
but the same parameter should be available for generic sched_scan calls
as well and this can now be reached through the new PNO start sequence.

Scan request failures are observed in wpa_supplicant debug log when
Android framework starts PNO scan in driver via ctrl interface command
'set pno 1' and wpa_supplicant also tries to issue a scan request after
PNO has started in the driver.
Some drivers may reject a normal scan request when PNO is already in
progress. wpa_supplicant should consider PNO status before issuing start
scan request to the driver. Otherwise, wpa_supplicant will get failures
from driver for the scan request and it will end up rescheduling scan
request in periodic interval and get a start scan request failure for
each attempt.
In order to avoid unnecessary scan attempt when PNO scan is already
running, PNO status is checked before issuing scan request to driver.

This patch resets the static interface_count to zero in case of
wpa_supplicant_driver_init() call for wpa_s which is in
INTERFACE_DISABLED state. This interface_count is used for the delay of
the scan which is now minimal for dynamically added interfaces. This may
collide with a scan for another interface, but the same is true for any
chosen delay in this scenario. Also the state change to DISCONNECTED is
moved to wpa_supplicant_driver_init() so it will move from
INTERFACE_DISABLED to INACTIVE when there are no enabled networks.

An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.
The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.

On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).
If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.

wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P

Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using

It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.
Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).
In addition to indicating the error cases for persistent groups, all
this type of PSK failures end up in the client removing the group with
the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

Previously, wpa_supplicant behavior in WEP configuration was to try to
mimic a device that is not aware of WPA/WPA2 and as such, it tried to
connect to a WPA/WPA2 AP with the assumption that the AP could be
providing support for both WEP and WPA/WPA2 stations in the same BSS.
Such APs could have been used during transition from WEP to more secure
options, but that type of deployment have not been used in large number
and are not really of much use anymore taken into account that more or
less all new devices support WPA/WPA2. That combined with the preference
to deprecate WEP justifies removing this use case and making WEP
networking matching more strict by using the knowledge of AP advertising
WPA/WPA2 as an indication of WEP not being supported.

To better support the IBSS/RSN mechanism, wpa_supplicant has to be able
to detect a possible peer reboot and in this case it should start a new
EAPOL handshake.
To perform such reboot detection wpa_supplicant has to perform an Open
Authentication by sending an Authentication frame and then replying to
it. IF an Authentication frame is received when the key have already
been exchanged, wpa_supplicant understands that the peer has rebooted
and can reset its state machine.
Whenever a new peer is added to the IBSS wpa_supplicant will start the
Open Authentication and only after having accomplished it will start the
key exchange. If the driver does not support Authentication frame
exchange initiated from user space, this step is skipped to maintain
previous behavior (just go through EAPOL-Key frame processing).
The Open Authentication was partly supported by the Linux kernel but now
wpa_supplicant can register for Authentication frames, handle it in
userspace and so avoid any possible race condition.
